This team should be very competitive in a 12 teamer. I think you factored the scoring format very well into your later picks by grabbing some SLG guys (Pena, Chris Davis.) I'm not sure how it scales in a 12 team league, but your low 100's steals might be a little light. Honestly I'm not in the know about CS rates so that may skew things a little bit with NSB as a stat as opposed to straight SB.
